IMPROVEMENT INSHUTTER BOWERS AND FASTENERS.

Specification forming part of Letters latefit N 0. 195,309, datedSeptember 18, 1877; application filed T Y June 25, 1877.

To all whom it may concern Be it known that 1,THoMAs B. ROGERS, J r., ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Fastener and Adjuster for Shutters, 850., of which thefollowing is a specification:

Figures 1 and 2 are plan views of one form of my improved shutteradjuster and fastener. Fig. 3 is a vertical section taken on line now inFig. 1. Fig. 4isa side elevation of a modified form. Fig. 5 is a planview. Fig. 6 is a plan view, showing the shutter open. Fig. 7 is adetail view of the catch that holds the shutter gpen. Fig. 8 is amodified form of adjusting- Similar letters of reference indicatecorresponding parts.

The object of my invention is to provide a convenient and reliableshutter fastener and adjuster; and it consists, mainly, in a novelcombination of parts, as hereinafter more fully described and claimed.

In the drawings, Figs. 1, 2, and 3, A is the shutter; B, thewindow-frame. O is a bar, having one end curved and jointed to an ear,D, that projects diagonally from the shutter toward the window-casing.In the bar (J there is a slot, at, and at the sides of the slotcountersunk or concave places are formed for receiving the convexportion of the thumbscrew E, the threaded portion of which is receivedby a plate, 11, secured to the windowsill. A catch, 0, pivoted betweenears d, engages the bar when the shutter is closed, and prevents theshutter from being opened until it is disengaged. The inner surface ofthe nib g of the catch is serrated, so that it may engage the bar 0 withcertainty.

The shutter is adjusted by means of this device by loosening thethumb-screw E, releasing the catch c, and swinging the shutter open tothe desired point, and clamping it by means of the screw. The engagementof the convex portion of the screw with the concavities of the barinsures the fastening of the shutter in any desired position.

The inner end of the bar 0 is curved upward, so that it may readily passover the stop-bead of the window-stool.

The device represented in Figs. 4, 5, 6, and

7 consists of two bars, A B, jointed together at a the fastening-bar 0cars D, and catch E. The bar A has formed upon it a boss, b, which issecured by the flange or lip 0, formed on the disk F, which is attachedto the window-sill. The lever is further secured to the disk by therivet d. The bar B is pivoted between ears D, that are attached to theshutter, and project diagonally toward the window-casing. A slotted bar,0 is jointed to the bar B at e, and is secured to the bar A by aclamping-screw, f. The screw f has upon its under surface a convexprojection, that is received by concavities formed in the surface of thebar 0 along the slot. The bar B is provided with a nib, 9, that iscapable of engaging the bar A when the shutters are closed.

The space between the ears D is sufficient to admit of springing the barB, so as to disengage the nib g from the bar A. The centers of the jointin the ears D and the center of the joint in the disk F are arranged inrelation to each other in such a manner as to lock the bars whenparallel to the shutter, and to prevent the shutter from being openeduntil the window is raised and the bars moved together toward the inneredge of the windowstill.

The bars, and consequently the shutter, may be clamped in any positionby means of the slotted bar 0 and the clamping-screw f.

When the shutters are wide open the bar B is engaged by a catch, E,which is pivoted between ears i, that project from a plate attached tothe shutter. This catch is provided with a shoulder, It, which preventsit from dropping below a horizontal line drawn through its pivot, andthe same shoulder projects sutficiently to touch the bar B when theshutter is open, and throw the catch over in case the catch shouldremain in a vertical position when disengaged from the bar.

A plate, I, is attached to the window-stool to receive the end of thescrew f when the shutters are closed.

The bar B, in the present case, is curved,

to receive the screw j,- but by providing an car on the bar A this curvemay be avoided. The slotted bars are described as having concavities intheir upper surface; but they may be made plain,or the bar 0 (shown inFig. 8) may be substituted for them. In this bar notches a? are formedfor receiving the thumbscrew that clamps the bar.

I have described my improvements as applied to shutters; but I do notconfine myself to such application, as the fastener and adjuster may beattached to scuttle-lids, fanlights, doors, trunk-lids, &c.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patout- 1. A shutter fastener and adjuster provided with aslotted bar, 0 or 0 having concavities for the reception of the convex.por' tion of the thumb-screw E, substantially as shown and described.

2. The bars A B, jointed together, as described, the slotted bar 0 andclamping-screw f, in combination, as set forth.

3. The nib g, in combination with the bars A B, as and forthe purposespecified.

4. The catch E, having the shoulder is, in combination with the bars AB,substantially as shown and describedi THOMAS B.'ROGERS, JR.
